Green Fire Tetra (Aphyocharax rathbuni) a new one for me:)

bgarthe · Jul 10, 2026

Just got these Green Fire Tetras acclimated and in my QT. Since this morning, they’ve colored up really well and they recently had a small meal. The green and red combo is pretty sharp on a smaller fish and I think they’ll go well in the 33g long with the Red Cherry Tetras and Yellow Phantom Tetras which are also smaller.

I forgot about these! I used to have a few back in the not knowing one of this fish one of that fish days way back. The colors are striking!

Those are really pretty fish. Off the beaten tetra path for sure.

Nice colours. Their body shape is a pleasing contrast to many tetras as well.

Are these too small to keep with angelfish?

bgarthe · Sep 5, 2026

Yes for an Angel bigger than a half dollar and certainly one any bigger. It kinda depends on how old the green fires are and their size.

My biggest GFTs might be ok with a middle aged Angel, but the smaller ones would be food for sure. My Angel is not with my GFTs as he is big and moody.

Possibly, if they grow up together they might be OK, but not guaranteed .I once had angelfish with neon tetras, the tetras were never eaten but they were already adults when I added the very small angels. The green fire tetras can apparently get to 2”, but they are slim. No definite answer, but I wouldn’t risk adding them to a tank with adult angels.

I love my school of A. rathbuni. I may get a few more to add to my group once my tank is done with the remodeling. They may be the perfect tetra?
